“…The results indicated that in the sitting position, the curvature of lumbar lordosis decreased by 50% and PT increased by 25%. Other studies yielded similar results, which can be summarized as a straightened curve in the lumbar region, pelvic retroversion, and forward displacement of sagittal balance [2][3][4][5]11 . Hey et al compared the spinal sagittal alignment in three weightbearing positions (standing, erect sitting, and natural sitting) in healthy subjects and found that LL decreased by approximately 80% in the natural sitting position; furthermore, the curvature of the trunk was vaguely C-shaped 3 .…”

“…Previous studies have investigated the basic changes occurring in the lumbar and pelvic regions when moving from the standing to sitting position in healthy subjects, which can be summarized as a straightened curve in the lumbar region (decreased lumbar lordosis) and pelvic retroversion (increased pelvic tilt) [1][2][3][4][5] . Spinal sagittal alignment is reported to greatly affect the clinical outcomes and quality of life 6,7 .…”

Objective: This study aimed to describe the changes in spinopelvic sagittal alignment in the sitting position after posterior lumbar fusion, and to identify the factors influencing unfused adjacent segment lordosis.Methods: Consecutive patients with lumbar degenerative disease who underwent posterior lumbar interbody fusion between December 2010 and April 2012 were recruited. Lateral full spine radiographs were obtained in the standing, erect sitting, and natural sitting positions. Spinopelvic parameters were measured preoperatively and at the final follow-up. Results: The data of 63 patients were analyzed in this study. The average age was 61.6±11.0 years. When changing from standing to sitting at the final follow-up, all spinopelvic sagittal parameters with the exceptions of pelvic incidence and thoracic kyphosis were significantly altered. The most noticeable changes occurred in the natural sitting position, with the spine slumped toward achieving a C-shaped sagittal profile. Multiple linear regression analysis revealed that when changing to a natural sitting position, age and fusion levels reflected the changes in lumbar lordosis (ΔLL), age and lumbosacral fusion reflected the changes in upper residual lordosis (ΔURL). Conclusion: The most noticeable changes in spinopelvic sagittal alignment occurred in the natural sitting position after lumbar fusion. Age, fusion levels, and lumbosacral fusion significantly influenced the differences in LL and URL between the standing and natural sitting position. These characteristics should be fully considered when planning spinal realignment surgery and investigating the etiological factors of junctional complications.

“…Lord et al 8) reported that the occurrence of lumbar lordosis while standing was nearly 1.5 times higher on average than the occurrence of lumbar lordosis while sitting. We had also reported about the difference of lumbo-pelvic alignment between the standing and sitting position 9,10) . Shum et al showed that in patients with low back pain, not only the significant limitations in the range of movement of the lumbar spine and hip during sitto-stand also the altered coordination within the lumbar spine-hip joint complex 11) .…”

Introduction: Most people in modern societies spend the majority of their time sitting. However, sagittal spinal alignment is usually analyzed in the standing position. For understanding the symptoms associated with postural changes, this alignment is better to be analyzed in various positions. The purpose of this study was to investigate lumbo-pelvic relationships between standing up and sitting (sit-to-stand) motion. Methods: The study subjects were 25 healthy young adult volunteers without any spinal symptoms. The following parameters were measured, namely, intervertebral range of motion (IV ROM), lumbar lordotic angle (L1L5), sacral slope (SS), pelvic tilt (PT), and pelvic incidence (PI), on lateral whole-spine radiographs while sitting upright, sitting anterior flexed (anteflexed), standing anteflexed, and standing upright. Results: The measurements of spinopelvic parameters during sit-to-stand motion (sitting upright, sitting anteflexed, standing anteflexed, standing upright, respectively) were as follows:

“…And diffuse idiopathic skeletal hyperostosis and ossification of the ligamenta flava in the thoraco-lumbar spine often present together with cervical OPLL 19) . Suzuki presented that the elderly persons also lose the lumbo-pelvic compensation mechanism because of the rigid spine 20) . It is, therefore, possible at least in part that the global spinal compensatory mechanisms are waned in rigid spine in the presence of OPLL.…”
